The Keysight Technologies 20-channel data acquisition system unit has a sampling rate of 3Msps with RS calibration. Its versatility includes the use as a data logger, data acquisition front-end and switch system. It measures and converts temperature with thermocouples, RTDs and thermistors, DC and AC voltage, 2-wire and 4-wire resistance, frequency and period, and DC and AC current. Each channel is independently configurable. Built-in signal conditioning means users can measure 11 different functions without any added cost or hassle of external signal conditioning Accessories. It is used for data logging.
